Kelly Osbourne Blasts Christina Aguilera, Continues Decade-Long Feud

Kelly Osbourne may be British, but you'll have to excuse her French.

After nearly a decade of mutual mudslinging, Kelly Osbourne took a cheap shot at Christina Aguilera on a recent episode of E!'s "Fashion Police." When Joan Rivers commented that Xtina looked "stuffed into" the Givenchy dress she wore last month and called her "Snooki's Scandinavian cousin," Osbourne didn't hesitate to contribute her two cents. Kelly laughed and said, "Maybe she is just becoming the fat bitch she was born to be. She was a c**t to me. She called me fat for so many f****** years." Sensing her carpe diem (and possibly karmic) moment, the Brit continued, "So you know what? F**k you! You're fat too!"

Back in 2002, Aguilera allegedly said Osbourne was "the nastiest person [she'd] ever seen," and that she was "bitter and twisted about life." In return, Kelly supposedly called Christina "one of the most disgusting human beings in the entire world" and added, "I've seen drag queens who look better. She has a bad mouth...but she's all talk." The feud nearly came to blows at a party, when Christina reportedly put Kelly in a headlock and warned her to do her trash-talking in person. It would ! seem tha t nearly ten years later, their sentiments haven't changed much.

It's hard to say whether or not Christina will strike back at her long-time rival, but we're thinking the two should just give it up and make nice. Seriously, our early-American history's a tad rusty, but we seem to remember the last time the British got in a fight with some Americans, and it didn't go particularly well.

Christina isn't the only person who's been on the receiving end of Kelly's wrath.

Last month, Kelly had words with her ex-fiance, Luke Worrall. When a follower asked Worrall why he'd ever dated Osborne and suggested that leaving her was a smart move, the reality star fired back. She tweeted, "You've made it very clear u only dated me 4 my life style (sic) but sh*t tweets about me the day im (sic) @ a funeral u have hit a new low." Osborne was referring to attending the London funeral of her friend, Amy Winehouse, and continued to give her ex a piece of her mind. "It was fine when Kellyphant ass was paying 4everything wasn't it?" We're thinking it's probably good that the two split up, no?

Osbourne may be justified in some of her comments, but it would appear that, at times, her delivery sucks.

After chasing off two car thieves in London last month, Kelly joked, "I did not realize I was that scary." Apparently she is, since she nearly got in a scuffle the very next night with another patron at the shi-shi restaurant Nobu. She tweeted, "Really makes me sad that the staff at nobu allowed a man to try and fight me because I asked him to stop slamming his glass on the table!" Since we've been dining peacefully for decades, we're not sure how far one ! has to g o to pick a fight in a public restaurant. We're thinking that, just maybe, the "direct approach" just isn't working for Kelly.

Let's bury the hatchet, ladies, and not in each other's backs.
